sufficient illumination of the high-
way without blinding other motor-
Fig. 65-Re/easing Retaining
ists. When light aiming is necessary
Ring
it is advisable to contact a Chevrolet
dealer who has special equipment for this purpose.
The parking, stop and tail lamp bulbs may be reached by
removing the rim clamp screws, rim and lens. Push the bulb in
slightly and turn it counterclockwise as far as possible and
pull it out of socket. Push new bulb into place and turn it
clockwise to lock it. Install rim and lens.
Thermal Circuit Breakers and Fuse
One circuit breaker in the lighting circuit for the headlamps
and tail lamps eliminates a fuse in the circuit. When current
load is too heavy, the circuit breaker opens and closes rapidly,
reducing current sufficiently to protect wiring until the cause
.is eliminated. A second circuit breaker in the circuit for other
lamps prevents short circuit or overload in that circuit from
disabling the headlamp circuit. Both circuit breakers are in-
corporated in the light switch. A fuse in the light switch
protects the instrument panel light circuit .

TUBELESS TIRES
Tubeless tires mounted on one piece wheels with drop
center rim are used on all 1956 Chevrolet trucks. These tires
have a safety inner liner which, if punctured, tends to cling
to the penetrating object forming a partial seal until the
object is removed from the tire. It is therefore now even more
essential to conduct a periodic visual tire inspection to remove
foreign objects from the tubeless tire than with the previously
used tube type tire. When the tubeless tire has been punc-
tured it should be repaired as covered in this section .
